Abstract

La présente invention concerne un système de surveillance à distance comprenant : une pluralité de dispositifs de collecte de données qui collectent respectivement des données de dispositif comprenant des informations indiquant des conditions de fonctionnement et/ou des contenus de fonctionnement d'un ou de plusieurs instruments d'équipement ; et un dispositif d'agrégation de données qui communique avec la pluralité de dispositifs de collecte de données et reçoit et agrège les données de dispositif collectées par la pluralité de dispositifs de collecte de données. Les dispositifs de collecte de données stockent des informations de définition côté collecte qui définissent un ou plusieurs éléments destinés à extraire les données de dispositif d'un groupe de données comprenant les données de dispositif acquises à partir du ou des instruments d'équipement, extraient les données de dispositif sur la base des informations de définition côté collecte et envoient au dispositif d'agrégation de données une requête pour mettre à jour les informations de définition côté collecte lorsque des conditions prédéterminées sont remplies. Le dispositif d'agrégation de données stocke des informations de définition côté agrégation qui définissent un ou plusieurs éléments pour la pluralité de dispositifs de collecte de données pour extraire respectivement les données de dispositif du groupe de données et transmet des informations de mise à jour sur la base des informations de définition côté agrégation au(x) dispositif(s) de collecte de données lorsque les dispositifs d'agrégation de données ont reçu la requête du ou des dispositifs de collecte de données, et le(s) dispositif(s) de collecte de données qui ont reçu les informations de mise à jour mettent à jour les informations de définition côté collecte au moyen des informations de mise à jour.
